[0045] Some existing cooking utensils usually have air holes on the pot cover to balance the air pressure inside and outside the cooking utensil. Such a pot cover with only air holes cannot maintain a certain air pressure in the cooking utensil, which is not convenient for fast cooking. In order to achieve the purpose of fast cooking, there are micro-pressure pot covers on the market. The micro-pressure valve on the micro-pressure pot cover is usually complex in structure and inconvenient to operate.
[0046] To solve the above problems, as shown in Figures 1 to 10 The present application first provides a pot cover to facilitate user control of the micro-pressure valve.
[0047] As shown in Figure 2 and Figure 6As shown, specifically, the pot cover comprises a body 10 and a valve assembly 20, wherein: the body 10 comprises a cover body 11, and the cover body 11 is provided with a gas hole 111; the valve assembly 20 is arranged on the cover body 11, and the valve assembly 20 comprises a valve seat 21, a valve body 22, a valve core assembly 23 and a knob 24, the valve seat 21 is fixedly arranged at the gas hole 111 of the cover body 11, the valve body 22 is arranged on the valve seat 21 and has an avoiding hole 221, the valve core assembly 23 is arranged in the valve body 22 in a liftable manner and communicates with the gas hole 111; the knob 24 has one of a sliding rod 241 and a sliding groove 231, the other of the two is arranged on the valve core assembly 23, the sliding groove 231 is arranged in an inclined manner, the sliding groove 231 has a low position and a high position, and the sliding rod 241 passes through the avoiding hole 221 and cooperates with the sliding groove 231, so that when the sliding rod 241 is at the high position of the sliding groove 231, the valve core assembly 23 is in a raised state, and when the sliding rod 241 is at the low position of the sliding groove 231, the valve core assembly 23 is in a liftable state.

Since the height of the sliding rod 241 remains unchanged, and the sliding groove 231 is arranged in an inclined manner, the sliding rod 241 can drive the valve core assembly 23 to lift relative to the valve body 22 when sliding in the sliding groove 231; specifically, when the valve core assembly 23 is in a liftable state, the valve core assembly 23 can lift in the valve body 22 according to the gas pressure in the pot body, when the gas pressure in the pot body is lower than the gravity of the valve core assembly 23, the valve core assembly 23 is in a state relative to the gas hole 111, and the gas in the pot body cannot be discharged through the gas hole 111, so that the gas pressure in the pot body can be increased, when the gas pressure in the pot is greater than the gravity of the valve core assembly 23, the gas can push the valve core assembly 23 to discharge through the gas hole 111, so that the pot is maintained in a state of micro-pressure, and rapid cooking is realized. When the valve core assembly 23 is in a raised state, the valve core assembly 23 lifts relative to the valve body 22 to open the gas hole 111, and the gas in the pot body can be discharged through the gas hole 111, so that the gas pressure in the pot body can be reduced, and cooking in a normal pressure working state is realized. The user only needs to turn the knob 24 by hand to control the valve core assembly 23, realize the above-mentioned effect, and the operation is convenient.
[0049] In other embodiments, the low position and the high position of the sliding groove 231 can each be provided with a limiting portion (not shown in the figure), and the sliding rod 241 can be limited in the limiting portion. When the sliding rod 241 is in the limiting portion of the sliding groove 231, the sliding rod 241 can be kept in the limiting portion, i.e., by matching the sliding rod 241 with the limiting portion of the sliding groove 231, so that the sliding rod 241 can be stably kept in the low position or the high position in the sliding groove 231 without the action of external force, thereby enabling the valve core assembly 23 to be stably kept in the raised state or the liftable state, without the need for the user to continuously hold the knob 24, facilitating the user operation. The limiting portion can be a support platform, at this time the sliding rod 241 can be lapped on the support platform, or a limiting protrusion is provided on the sliding groove 231, and the limiting protrusion forms a limiting step with the bottom wall of the sliding groove 231, so that the sliding rod 241 is clamped in the limiting portion. Of course, the limiting portion can also be a groove, and the sliding rod 241 can be clamped in the groove.
[0050] Reference Figure 1 and Figure 2 As shown in FIGS. 1, 2 and 3, the body 10 further comprises a handle 12, which is provided on the cover 11 and is spaced apart from the valve assembly 20. The provision of the handle 12 can facilitate the user to pick up the pot cover, and on the other hand, by spacing apart the handle 12 and the valve assembly 20, it is beneficial to assemble and control the valve assembly, avoiding the complexity of structure caused by the integration of the two.
[0051] As shown in FIGS. 1, 2 and 3, the body 10 further comprises a handle 12, which is provided on the cover 11 and is spaced apart from the valve assembly 20. The provision of the handle 12 can facilitate the user to pick up the pot cover, and on the other hand, by spacing apart the handle 12 and the valve assembly 20, it is beneficial to assemble and control the valve assembly, avoiding the complexity of structure caused by the integration of the two. Figure 7 and Figure 10 As shown in FIGS. 1, 2 and 3, the body 10 further comprises a handle 12, which is provided on the cover 11 and is spaced apart from the valve assembly 20. The provision of the handle 12 can facilitate the user to pick up the pot cover, and on the other hand, by spacing apart the handle 12 and the valve assembly 20, it is beneficial to assemble and control the valve assembly, avoiding the complexity of structure caused by the integration of the two.
[0052] As shown in FIGS. 1, 2 and 3, the body 10 further comprises a handle 12, which is provided on the cover 11 and is spaced apart from the valve assembly 20. The provision of the handle 12 can facilitate the user to pick up the pot cover, and on the other hand, by spacing apart the handle 12 and the valve assembly 20, it is beneficial to assemble and control the valve assembly, avoiding the complexity of structure caused by the integration of the two. Figures 6 to 7As shown, in an embodiment, the valve core assembly 23 comprises a top block 232 and a valve core 233, the top block 232 is movably arranged on the valve body 22 and can abut against the valve core 233, the top block 232 is provided with a sliding groove 231, the sliding rod 241 is arranged on the knob 24, and the valve core 233 is movably arranged on the valve body 22. When the sliding rod 241 works from the low position to the high position of the sliding groove 231, the top block 232 descends relative to the valve body 22, and the valve core 233 descends relative to the valve body 22 under the action of gravity to disconnect the air hole 111 from the outside; when the sliding rod 241 works from the high position to the low position of the sliding groove 231, the top block 232 ascends relative to the valve body 22 and pushes the valve core 233 to ascend relative to the valve body 22 to connect the air hole 111 with the outside. Moreover, the valve core 233 and the top block 232 are arranged in a split structure, when the gas pressure in the pot body is greater than the gravity of the valve core 233, the gas pressure can also push the valve core 233 to ascend relative to the valve body 22 to the open state to open the air hole 111, so that the gas in the pot body can be discharged in time through the air hole 111, and when the gas pressure in the pot body decreases, the valve core 233 can descend relative to the valve body 22 to the closed state under the action of gravity to close the air hole 111, thereby preventing the gas pressure in the pot body from being too large to cause danger and improving the use safety. Wherein, the valve core 233 can be made of a material such as silica gel or rubber which has elasticity, so that the valve core 233 is more easily lifted when the gas pressure in the pot body is larger; the top block 232 can be made of the same material as the valve core 233, or other hard materials, so that the cooperation between the sliding rod 241 and the sliding groove 231 is more stable and reliable. Of course, in other embodiments, the valve core assembly 23 can also be a one-piece structure, so that the valve core assembly 23 as a whole can be controlled to ascend and descend relative to the valve body 22 by the knob 24 to open and close the air hole 111.
[0053] As shown in Figure 6 and Figure 9 , the side wall of the valve core 233 is provided with a gas port 2331, and the gas port 2331 is arranged along the circumference of the valve core 233. When the valve core 233 is in the open state, at least part of the side wall of the valve core 233 is exposed to the valve body 22, the gas port 2331 is opened, so that the gas in the pot body can be discharged through the air hole 111 and the gas port 2331, and the arrangement of the gas port 2331 along the circumference of the valve core 233 can improve the exhaust efficiency; when the valve core 233 is in the closed state, the side wall of the valve core 233 is blocked by the valve body 22, the gas port 2331 is blocked by the valve body 22, so that the gas in the pot body cannot be discharged through the air hole 111 and the gas port 2331.
[0054] As shown in Figure 5 , Figure 8 and Figure 9As shown, along the circumference of the valve core 233, the wall of the valve core 233 is divided into a gas permeable area 2332 and a gas blocking area 2333, and the gas port 2331 is arranged on the gas permeable area 2332; the knob 24 is rotatably sleeved on the valve body 22, the inner wall of the knob 24 is provided with a sliding rod 241 matched with the sliding groove 231, the outer wall of the knob 24 is provided with a handle 242, and the gas blocking area 2333 is arranged corresponding to the handle 242. The handle 242 can facilitate the user to control the rotation of the knob 24 relative to the valve body 22, and when the knob 24 rotates relative to the valve body 22, the sliding rod 241 can slide in the sliding groove 231, thereby driving the lifting block 232 and the valve core 233 to ascend and descend relative to the valve body 22. When the valve core 233 is in the open state, since the gas port 2331 is arranged on the gas permeable area 2332, and no gas port 2331 is arranged on the gas blocking area 2333, the gas in the pot body can be discharged through the gas hole 111 and the gas port 2331 arranged on the gas permeable area 2332, and will not be discharged from the gas blocking area 2333, and the handle 242 is arranged corresponding to the gas blocking area 2333, thereby preventing the user from being scalded by the high-temperature gas discharged from the gas port 2331 when holding the handle 242. The number of the gas port 2331 can be one, two, three or more, and the plurality of gas ports 2331 are arranged on the gas permeable area 2332 along the circumference of the valve core 233.
[0055] As shown in Figure 8 , the rotation angle of the handle 242 is α, and the shielding angle of the gas blocking area 2333 is β, wherein α≤β. The rotation angle of the handle 242 refers to the central angle of the region between the position of the handle 242 when the valve core 233 is in the open state and the position of the handle 242 when the valve core 233 is in the closed state along the circumference of the valve core 233; the shielding angle of the gas blocking area 2333 refers to the central angle of the region between the two ends of the gas blocking area 2333 along the circumference of the valve core 233. Moreover, the projection of the region between the position of the handle 242 when the valve core 233 is in the open state and the position of the handle 242 when the valve core 233 is in the closed state on the valve core 233 is completely located in the region between the two ends of the gas blocking area 2333. In this way, it can be ensured that the high-temperature gas discharged from the gas port 2331 will not flow towards the handle 242, further preventing the user from being scalded by the high-temperature gas discharged from the gas port 2331 when holding the handle 242. It should be noted that the rotation angle of the handle 242 is α and the shielding angle of the gas blocking area 2333 is β, which can be the angles shown in the figure, or can be adjusted according to actual needs, and the embodiments of the present application do not make specific limitations here. Generally, the rotation angle of the handle 242 is α≥40°, so as to facilitate the user to operate.
[0056] As shown in Figure 4 , the valve seat 21 is provided with a protrusion 213, the protrusion 213 is arranged along the circumference of the valve body 22 and located between the valve body 22 and the knob 24, so as to limit the knob 24 and prevent the knob 24 from sliding relative to the valve body 22 along the radial direction of the valve body 22.
[0057] As shown in Figure 9 one embodiment, the inner wall of the valve body 22 is provided with a guide rib 222 along the length direction of the valve body 22, and the air blocking area 2333 of the valve core 233 is provided with a guide groove 2334 matched with the guide rib 222. The length direction of the valve body 22 is the direction in which the valve core 233 ascends and descends relative to the valve body 22. In this way, the ascending direction and range of the valve core 233 can be limited by the cooperation of the guide rib 222 and the guide groove 2334, and the valve core 233 is prevented from rotating relative to the valve body 22. Furthermore, the guide groove 2334 is arranged in the air blocking area 2333, so that the guide groove 2334 does not occupy the space of the air port 2331. In another embodiment, the air blocking area 2333 of the valve core 233 can be provided with a guide rib 222, and the inner wall of the valve body 22 is provided with a guide groove 2334 matched with the guide rib 222.
[0058] When the valve core assembly 23 is a one-piece structure, the inner wall of the valve body 22 is provided with a guide rib 222 along the length direction of the valve body 22, and the outer wall surface of the valve core assembly 23 is provided with a guide groove 2334 matched with the guide rib 222. Alternatively, the outer wall surface of the valve core assembly 23 can be provided with a guide rib 222, and the inner wall of the valve body 22 is provided with a guide groove 2334 matched with the guide rib 222. In this way, the ascending direction and range of the valve core assembly 23 can be limited by the cooperation of the guide rib 222 and the guide groove 2334, and the valve core assembly 23 is prevented from rotating relative to the valve body 22.
[0059] As shown in Figure 10 further, one of the inner wall of the valve body 22 and the outer wall surface of the top block 232 can be provided with a guide rib 222, and the other is provided with a guide groove 2334 matched with the guide rib 222, and the guide rib 222 is arranged along the length direction of the valve body 22. In this way, the ascending direction and range of the top block 232 can be limited by the cooperation of the guide rib 222 and the guide groove 2334, and the top block 232 is prevented from rotating relative to the valve body 22.
[0060] As shown in Figure 4 and Figure 9 the top end of the valve body 22 has a groove 223, and the lower edge of the valve core 233 abuts against the bottom wall of the groove 223 in the closed state of the air hole 111. In this way, the valve core 233 can be stably kept in the closed state by the groove 223, and the lower edge of the valve core 233 abutting against the bottom wall of the groove 223 can also play a sealing role, further preventing the gas in the pot from being discharged through the air hole 111 and the air port 2331, and improving the reliability of the valve assembly 20 in closing the air hole 111.
[0061] As shown in Figures 2 to 4As shown, the valve seat 21 is fixed to the cover body 11, and a sealing ring 25 is arranged between the valve seat 21 and the cover body 11.
